DESCRIPTION OF CHANGES:

The Gaea-C5 OS upgrade changed the version numbers for stack-intel and stack-cray-mpich. This PR updates the module files to point to the new version numbers.

Hello @GeorgeGayno-NOAA I have included updates for building ufs-utils in a container provided by @mark-a-potts. This is work being coordinated with @aerorahul (@WalterKolczynski-NOAA added since Rahul is on leave) and references NOAA-EMC/global-workflow Issue #3025.
For links to the fix directories, we don't want to have the fix directories in the container so did not update link_fixdirs.sh.
Please let me know if including the container build is okay, and if so, how we should handle link_fixdirs.sh. Maybe a warning message?
Thanks!

@GeorgeGayno-NOAA Sorry about that! Code is finalized and is consistent with other global-workflow submodules. Thanks.
